Consider a junction that connects three pipes A, B and C. What can we say about the mass flow rates in each pipe for steady flow

Elis [28]

Answer:

The statement regarding the mass rate of flow is mathematically represented as follows $\Rightarrow \rho \times Q_{3}=\rho \times Q_{1}+\rho \times Q_{2}$

Explanation:

A junction of 3 pipes with indicated mass rates of flow is indicated in the attached figure

As a basic sense of intuition we know that the mass of the water that is in the pipe junction at any instant of time is conserved as the junction does not accumulate any mass.

The above statement can be mathematically written as

$Mass_{Junction}=Constant\\\\\Rightarrow Mass_{in}=Mass_{out}$

this is known as equation of conservation of mass / Equation of continuity.

Now we know that in a time 't' the volume that enter's the Junction 'O' is

1) From pipe 1 = $V_{1}=Q_{1}\times t$

1) From pipe 2 = $V_{2}=Q_{2}\times t$

Mass leaving the junction 'O' in the same time equals

From pipe 3 = $V_{3}=Q_{3}\times t$

From the basic relation of density, volume and mass we have

$\rho =\frac{mass}{Volume}$

Using the above relations in our basic equation of continuity we obtain

$\rho \times V_{3}=\rho \times V_{1}+\rho \times V_{2}\\\\Q_{3}\times t=Q_{1}\times t+Q_{2}\times t\\\\\Rightarrow Q_{3}=Q_{1}+Q_{2}$

Thus the mass flow rate equation becomes $\Rightarrow \rho \times Q_{3}=\rho \times Q_{1}+\rho \times Q_{2}$

From the isometric view orientation resource, what are the four typical characteristics of a front view?

Natasha_Volkova [10]

From an isometric view orientation resource, the four (4) typical characteristics of a front view include the following:

The front view graphically shows the length and height of an object
The front view has the least amount of hidden lines.
The front view must be chosen first.
The front view's orientation influences the other views.

<h3>What is an isometric sketch?</h3>

An isometric sketch is also referred to as an isometric drawing and it can be defined as a graphical (pictorial) representation of a physical object in technical and engineering drawings, especially by drawing all its three dimensions (3D) at full scale.

<h3>The five characteristics of isometric sketches.</h3>

In technical and engineering drawings, the five (5) characteristics of isometric sketches include the following:

The final image isn't distorted.
The image is in three dimensions (3D).
The final image is drawn to full scale.
The image are all uniformly foreshortened.
They are drawn using vertical lines and horizontal lines.

shtirl [24]

Electronic returnless fuel systems use an in-line fuel supply pump.

<h3>What is the role of electronic Returnless fuel systems?</h3>

Electronic returnless EFI systems is known to bean “On Demand” returnless EFI systems due to the fact that it make use of fuel tank pressure sensor to examine fuel pressure.

Therefore, one can say that an Electronic returnless fuel systems use an in-line fuel supply pump.
